JPH07105971B2 - Equal distribution method between automatic call receiving stations - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an automatic equalization method among called stations in an exchange network system having a plurality of automatic private branch exchanges.

[Conventional technology]

Conventionally, even distribution of incoming calls in an automatic private branch exchange having an automatic incoming call distribution function is possible only within the own station.

[Problems to be Solved by the Invention]

If the above-mentioned conventional automatic private branch exchange having the automatic incoming call distribution function constitutes a switching network and the station line trunk and the automatic incoming call distribution reception desk are distributed to each station, the incoming call equalization between the offices is equalized. No distribution is possible. In addition, each station requires a management information system for controlling automatic incoming call distribution.

[Means for Solving the Problems]

The automatic call-distributing call equalizing system between call stations according to the present invention is an exchange network system that includes at least two automatic private branch exchanges and uses a common line signaling method for transmitting and receiving signals between stations. A means for monitoring the status of the trunk, a means for receiving the automatic call distribution reception desk of each station in the same group, a means for identifying which station belongs to the automatic call distribution reception desk, and a station line trunk for each station in the same group A means for identifying which station the trunk belongs to and a long-empty automatic reception distribution reception stand in the available state, select from a group that has been pre-assembled and select the station trunk and automatic reception distribution. It is equipped with a means for connecting to the reception desk for each station, and the station line incoming call of each station is evenly distributed to the reception desk for automatic reception distribution of each station in a state where the station line trunk and the reception desk for automatic incoming distribution are distributed to each station. It is configured to centrally manage that.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

Referring to FIG. 1 showing an embodiment of the present invention, at the automatic private branch exchange A at the time of initial setting or setting of station data from a maintenance terminal, station identification information of the station A and an automatic call distribution reception board.
From the central processing unit 122, the extension numbers of 100 and 101, the reception board group numbers to which these reception boards belong, and the routes and trunk numbers of the office line trunks 130 and 131 are controlled by the control circuit 121 and I / O.
Management information system 1 via interface circuit 113
Send to 14. Further, in the automatic private branch exchange B, the station identification information of the station B at the time of the initial setting or the setting of the station data from the maintenance terminal, the extension numbers of the automatic incoming call distribution reception boards 200 and 201, and the reception board group number to which these reception boards belong And trunk trunk
The route and trunk numbers of 230 and 231 are stored in the main storage device 223 from the route information of the station A to which the management information system 114 is connected. The common line control device 233, the digital trunk 232, the digital trunk 132, the common line control device. 13
3, sent to the management information system 114 via the central processing unit 122, the control circuit 121, and the I / O interface circuit 113. In addition, call reception and recovery information for the station line trunks 130, 131, 230, 231 of each station and automatic reception distribution reception desks 100, 101, 200, 20
Information such as the absence, logon and off during the idle talk of 1 is also sent to the management information system 114 through the same route as above.

Next, when an incoming call is actually received on the central line trunk 230, the management information system 114 detects this, and the management information system 114 automatically receives the incoming call from the incoming call reception desks 100, 101, 200, 201 in the receiving desk group which is a preset destination. If you select the longest reception board 100 that is empty from the reception ready status, the status of this reception board 100 is disabled and the station to which the reception board 100 was previously received, the extension number, and the call signal transmission. The information, the station to which the trunk line belongs, the route, the trunk number, and the call back sound transmission information are sent to the central processing unit 122 via the I / O interface circuit 113 and the control circuit 121. As a result, the central processing unit 122 selects an empty channel of the digital trunk 132 which is a route to the station B, and the central processing unit 122, the digital trunk 132, the digital trunk 232 and the common line control unit 233 are used to perform central processing. Central line trunk 230 and digital trunk 23 in processor 222
Send information to connect 2 and. The central processing unit 222 of the station B operates the time division switch 220 between the line trunk 230 and the digital trunk 232. In the central processing unit 122, a call back tone is sent to the digital trunk 132 corresponding to the digital trunk 232 to which the office line trunk 230 is connected,
While sending a call signal to the reception desk 100,
Office line trunk 230 and reception board for management information system 114
Sends information that the connection with 100 was completed normally. The management information system 114 manages the reception board 100 in an automatic incoming distribution call receiving state and the office line trunk 230 in a distribution status to the reception board group. As a result, it becomes possible to evenly distribute the incoming calls to the automatic incoming call distribution reception desks distributed to a plurality of stations in the network. Note that the management information system 114 similarly manages the response and recovery of the automatic incoming call distribution reception board 100, the recovery of the office line trunk 230, and the like.

〔The invention's effect〕

As described above, according to the present invention, it is possible to equally distribute incoming calls among the stations of the switching network system. In addition, this even distribution and the operating states of all stations can be managed and controlled at one place, and the number of management information systems can be reduced.
